Are you stranded because your car’s key fob is not working? A broken key fob can be frustrating, especially if you’re in a hurry or in an unfamiliar location. Fortunately, there are several methods to start your car even with a non-functional key fob. In this article, we will explore the different ways to start your car, the tools you may need, and provide step-by-step instructions to help you get back on the road.
Understanding Key Fobs and Their Functions
Before we dive into the solutions, it’s essential to understand how key fobs work and their role in starting your car. A key fob, also known as a remote keyless entry system, is a small device that uses radio frequencies to communicate with your car’s computer. The key fob sends a signal to the car’s receiver, which then unlocks the doors, trunk, or starts the engine. Key fobs can be powered by batteries, and their lifespan varies depending on the manufacturer and usage.
Causes of a Broken Key Fob
There are several reasons why your key fob may not be working. Some common causes include:
A dead battery, which is the most common reason for a non-functional key fob.
Water damage, which can occur if the key fob is exposed to moisture or submerged in water.
Physical damage, such as dropping the key fob or subjecting it to extreme temperatures.
Electronic malfunction, which can be caused by a faulty circuit board or a software glitch.
Solutions for a Broken Key Fob
If your key fob is not working, there are several methods to start your car. The approach you take will depend on the type of car you have, the age of the vehicle, and the tools you have available.
Method 1: Using a Spare Key
If you have a spare key, you can use it to unlock your car and start the engine. This is the simplest and most straightforward solution. Make sure you keep your spare key in a safe and accessible location, such as in your wallet or with a trusted friend or family member.
Method 2: Using the Emergency Start Procedure
Many cars come with an emergency start procedure that allows you to start the engine even if the key fob is not working. This procedure varies depending on the manufacturer, so it’s essential to consult your car’s manual or contact a dealership for specific instructions. In general, the emergency start procedure involves pressing a combination of buttons on the key fob or using a hidden key to unlock the doors and start the engine.
Tools and Equipment Needed
To start your car with a broken key fob, you may need some specialized tools and equipment. These include:
A spare key, which can be used to unlock the doors and start the engine.
A key fob battery replacement kit, which can be used to replace the dead battery in your key fob.
A key fob programming tool, which can be used to reprogram your key fob or add a new one to your car’s system.
A locksmith or a dealership’s services, which can be used to create a new key or repair a damaged key fob.
Step-by-Step Instructions
Here’s a step-by-step guide to starting your car with a broken key fob:
- Check your car’s manual or contact a dealership to see if your car has an emergency start procedure.
- If you have a spare key, use it to unlock the doors and start the engine.
- If you don’t have a spare key, try using the emergency start procedure.
- If the emergency start procedure doesn’t work, you may need to use a key fob programming tool or consult a locksmith or a dealership.
Preventing Key Fob Problems
While it’s impossible to prevent all key fob problems, there are some steps you can take to minimize the risk of a broken key fob. These include:
Keeping your key fob clean and dry to prevent water damage.
Avoiding exposure to extreme temperatures, which can cause the battery to drain or the electronics to malfunction.

Conclusion
A broken key fob can be a frustrating experience, but it’s not the end of the world. With the right tools and knowledge, you can start your car and get back on the road. Remember to always keep a spare key in a safe and accessible location, and consider using a key fob programming tool or consulting a locksmith or a dealership if you need help. By following the steps outlined in this article, you can minimize the risk of a broken key fob and ensure that you’re always ready to go. Always prioritize your safety and the security of your vehicle, and don’t hesitate to seek help if you’re unsure about any aspect of the process.
What should I do if my car key fob is broken and I need to start my vehicle immediately?
If your car key fob is broken and you need to start your vehicle immediately, you should first try to use the spare key, if you have one. Most car owners have a spare key that can be used in case the primary key is lost, damaged, or broken. Check your car’s manual or contact the manufacturer to see if there are any specific instructions for using the spare key. Additionally, if you have a keyless entry system, you may be able to use the emergency start procedure, which typically involves pressing a specific button or combination of buttons on the key fob.
It is essential to note that using a broken key fob or attempting to hotwire your car can cause damage to the vehicle’s electrical system or ignition. Therefore, it is recommended to seek the assistance of a professional locksmith or the car’s dealership as soon as possible. They can help you repair or replace the broken key fob, or provide you with a new set of keys. Moreover, if you are unable to start your vehicle, you may need to have it towed to a nearby repair shop or the dealership, where the necessary repairs can be made.
Can I start my car with a broken key fob if I have a push-button ignition system?
If you have a push-button ignition system and your key fob is broken, you may still be able to start your car. Many modern vehicles with push-button ignition systems have an emergency start procedure that allows you to start the vehicle even if the key fob is not functioning properly. This typically involves pressing a specific button or combination of buttons on the key fob, or using the spare key to start the vehicle. However, it is crucial to consult your car’s manual or contact the manufacturer to see if this procedure applies to your specific vehicle.
It is also important to note that some push-button ignition systems may require you to use the key fob in a specific way to start the vehicle, such as pressing the start button while holding the key fob close to the ignition. In some cases, the vehicle may not start if the key fob is not detected, even if you are using the correct procedure. If you are unable to start your vehicle, it is recommended to seek the assistance of a professional locksmith or the car’s dealership as soon as possible to avoid any further complications.
How can I get a replacement key fob if mine is broken or damaged?
If your key fob is broken or damaged, you can get a replacement from the car’s dealership or a professional locksmith. The dealership may have replacement key fobs in stock, or they can order one for you. A professional locksmith may also be able to provide you with a replacement key fob, or repair your existing one if it is damaged. Additionally, some online retailers may also sell replacement key fobs, but it is essential to ensure that the replacement is compatible with your vehicle’s make and model.
When getting a replacement key fob, you will typically need to provide proof of ownership and identification to verify that you are the rightful owner of the vehicle. The replacement process may also involve programming the new key fob to work with your vehicle’s ignition system, which can be done by the dealership or a professional locksmith. Moreover, if your key fob has additional features such as remote start or keyless entry, these features may need to be reprogrammed as well. It is recommended to contact the dealership or a professional locksmith to determine the best course of action for replacing your broken key fob.
Can I program a new key fob myself, or do I need to take it to a professional?
While it may be possible to program a new key fob yourself, it is not recommended unless you have experience with automotive electronics and programming. Modern key fobs often require specialized equipment and software to program, and attempting to program one yourself can result in errors or damage to the vehicle’s ignition system. Additionally, some vehicles may have specific security protocols in place that prevent DIY programming, and attempting to bypass these protocols can trigger the vehicle’s anti-theft system.
It is highly recommended to take your new key fob to a professional locksmith or the car’s dealership to have it programmed correctly. They will have the necessary equipment, software, and expertise to program the new key fob to work with your vehicle’s ignition system. Moreover, if you are using a replacement key fob from a third-party supplier, the dealership or locksmith may need to verify that it is compatible with your vehicle’s make and model. By having a professional program your new key fob, you can ensure that it works correctly and does not cause any issues with your vehicle’s electrical system.
How much does it cost to replace a broken key fob, and is it covered under warranty?
The cost of replacing a broken key fob can vary depending on the make and model of your vehicle, as well as the type of key fob you need. On average, a replacement key fob can cost anywhere from $50 to $200, depending on the complexity of the key fob and the programming required. Additionally, if you need to have the key fob programmed by a professional locksmith or the dealership, you may need to pay an additional fee for their services.
It is essential to check your vehicle’s warranty to see if the key fob is covered. Some manufacturers may cover the replacement of a broken key fob under the vehicle’s warranty, while others may not. Additionally, some warranty plans may only cover the replacement of the key fob if it is damaged due to a manufacturing defect, rather than wear and tear. If your key fob is not covered under warranty, you may need to pay for the replacement out of pocket. It is recommended to contact the dealership or a professional locksmith to determine the best course of action for replacing your broken key fob and to get a quote for the cost of replacement.
Can I use a third-party key fob replacement service, or should I go to the dealership?
While it may be possible to use a third-party key fob replacement service, it is generally recommended to go to the dealership or a professional locksmith. Third-party services may not have the necessary expertise or equipment to program the new key fob correctly, which can result in errors or damage to the vehicle’s ignition system. Additionally, some third-party services may use low-quality replacement key fobs that may not be compatible with your vehicle’s make and model.
Dealerships and professional locksmiths, on the other hand, have the necessary expertise and equipment to program the new key fob correctly. They will also be able to provide you with a high-quality replacement key fob that is specifically designed for your vehicle’s make and model. Moreover, if you have any issues with the replacement key fob, the dealership or locksmith will be able to provide you with support and assistance. While a third-party service may be cheaper, it is recommended to prioritize quality and reliability when it comes to replacing your key fob, and to go to the dealership or a professional locksmith for the best results.
How can I prevent my key fob from breaking or becoming damaged in the future?
To prevent your key fob from breaking or becoming damaged in the future, it is essential to handle it with care and avoid exposing it to harsh environments. Avoid dropping the key fob or subjecting it to extreme temperatures, as this can cause damage to the internal electronics. Additionally, keep the key fob away from water and moisture, as this can cause damage to the electrical components. You should also avoid using the key fob near other electronic devices that may interfere with its signal.
Regular maintenance can also help to extend the life of your key fob. Check the battery level regularly and replace the battery as needed. Clean the key fob regularly to remove dirt and debris that may accumulate on the surface. Additionally, consider using a key fob cover or case to protect it from scratches and damage. By taking these precautions, you can help to extend the life of your key fob and prevent it from becoming damaged or broken. If you do experience any issues with your key fob, it is recommended to contact the dealership or a professional locksmith as soon as possible to have it repaired or replaced.
